Description

Technical Field

[0001] This invention relates to the field of reaction vessel technology, specifically to a leak-proof reaction vessel discharge structure. Background Technology

[0002] Reactors are core reaction equipment in the fields of fine chemicals, pharmaceutical synthesis, coatings, and new material preparation. The bottom discharge valve is a key component for material discharge and isolation, and its sealing reliability directly determines the continuity of production, product purity, and on-site safety level. As existing reactors are generally equipped with top-discharge valves, bottom-discharge ball valves, or plunger valves to achieve bottom discharge control, leakage failures at the discharge point have occurred frequently during long-term industrial application, which has become a core pain point restricting the stable operation of the equipment. Summary of the Invention

[0003] The purpose of this invention is to provide a leak-proof reactor discharge structure, which aims to solve the problems of easy leakage at the interface of the reactor discharge part and easy blockage due to excessive discharge at one time.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A leak-proof reactor discharge structure is provided, wherein the bottom of the reactor is provided with a discharge pipe; the discharge structure includes a connecting pipe and a docking mechanism for connecting the discharge pipe and the connecting pipe; the connecting pipe is provided with a discharge mechanism for controlling the discharge of materials; The docking mechanism includes two limiting rings and two mounting rings. The two mounting rings are respectively fixed to the docking ends of the discharge pipe and the connecting pipe. The two limiting rings are assembled into a ring structure to engage the two mounting rings on their inner side and to be sleeved on the outer side of the docking ends of the discharge pipe and the connecting pipe. The two limiting rings are connected and fixed by a positioning ring. The discharge mechanism includes a blocking block that covers the end of the connecting pipe and a spring-loaded component. The spring-loaded component opens and pushes open the blocking block, causing the blocking block to disengage from the end of the connecting pipe.

[0005] In one embodiment, the upper end of the second limiting ring is attached to the discharge pipe and bent to form a step. A plurality of springs are evenly installed on the inner side of the upper end of the limiting ring. One end of the plurality of springs abuts against the step, and the other end abuts against the upper end of a movable ring. An elastic block is installed between the lower surface of the movable ring and the upper surface of the mounting ring located above it.

[0006] In one embodiment, the lower end of the second limiting ring is attached to the docking tube and forms a step. A plurality of springs are evenly installed on the inner side of the lower end of the limiting ring. One end of the plurality of springs abuts against the step, and the other end abuts against another movable ring. Another elastic block is installed between the upper surface of the movable ring and the lower surface of the mounting ring located below it.

[0007] In one embodiment, the outer side of the second limiting ring is provided with an external thread, and the inner side of the positioning ring is provided with an internal thread. The positioning ring is screwed onto the second limiting ring for connection and fixation.

[0008] In one embodiment, the cross-section of each of the limiting rings is semi-circular.

[0009] In one embodiment, the spring-loaded assembly includes a rotating rod that rotatably passes through the connecting tube and extends out of the connecting tube at both ends, with a plurality of stirring blades radially mounted on the rotating rod located within the connecting tube; A rotating wheel is installed at each end of the rotating rod located outside the connecting tube. The rotating wheel is connected to a cam via a timing belt. Two extrusion blocks are correspondingly provided on the outside of the connecting tube. The cam is in contact with the corresponding extrusion block. Each of the extrusion blocks is equipped with an extrusion rod at its bottom end, and the bottom end of the extrusion rod passes through a fixing block and is connected to the shielding block; the fixing block is fixed to the side of the connecting pipe. A reset spring is sleeved on the extrusion rod, with one end of the reset spring connected to the extrusion block and the other end connected to the fixing block.

[0010] In one embodiment, a drive motor is mounted on the top of the reactor via a coupling, and the output end of the drive motor extends into the interior of the reactor and is equipped with a stirring mechanism.

[0011] In one embodiment, the stirring mechanism includes a rotating rod, the top end of which is connected to the output end of a drive motor, and a transverse connecting rod is installed at the lower outer end of the rotating rod, the end of which is connected to a stirring rod.

[0012] In one embodiment, the outer edge of the bottom of the stirring rod is in contact with the inner wall of the reactor.

[0013] The advantages of this invention are: This invention provides a leak-proof reactor discharge structure. The reactor material is discharged through a discharge pipe and then further discharged by the discharge structure. Positional constraints are achieved between the installation ring and the limiting ring on the outer side of the discharge pipe and the connecting pipe, ensuring a stable connection between them. A connecting spring inside the limiting ring pushes out a movable block, keeping the elastic block in constant contact with the installation ring, thus locking the position of the discharge pipe and the connecting pipe. Finally, the threaded connection between the limiting ring and the positioning ring maintains the locked position between the discharge pipe and the connecting pipe, achieving a stable connection and effectively preventing leakage during discharge, thus improving overall stability during use.

[0014] Furthermore, during material discharge, to prevent blockage of subsequent pipelines due to excessive material discharge, the material's own weight impacts the stirring blades inside the discharge pipe and connecting pipe, causing the blades to rotate along the rotating rod. The rotating blades disperse the material as they rotate. The material then falls onto the surface of the baffle block. When a certain weight is accumulated and the rotating rod completes one revolution, the rotating wheel rotates synchronously. The rotating wheel drives the cam to rotate via a synchronous belt. The rotating cam compresses the extrusion block, causing it to move downwards. Simultaneously, the extrusion rod extends downwards, moving the baffle block and stopping its obstruction of the connecting pipe. The material then discharges from the bottom of the connecting pipe, achieving material discharge and preventing excessive material discharge that could cause blockage. This also ensures that the material inside the reactor reacts fully before being discharged.

[0015] Furthermore, materials are added to the interior of the reactor through the feed inlet at the top of the reactor. The output end of the drive motor is connected to the rotating rod. When the output end of the drive motor rotates, it synchronously drives the rotating rod to rotate. When the rotating rod rotates, it drives the connecting rod and the stirring rod to rotate. When the stirring rod is rotated by the rotating rod, the bottom end of the stirring rod fits into the bottom end of the inner wall of the reactor, thereby allowing the materials inside the reactor to react fully and reducing the possibility of incomplete reaction.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] See Figures 1 to 8 This example illustrates the main structure of a leak-proof reactor discharge structure. A drive motor 2 is mounted on the top of the reactor 1 via a coupling. The output end of the drive motor 2 extends into the reactor 1 and is fitted with a stirring mechanism. The stirring mechanism includes a rotating rod 3, the top of which is connected to the output end of the drive motor 2. A transverse connecting rod 4 is mounted on the lower outer end of the rotating rod 3, and the end of the connecting rod 4 is connected to a stirring rod 5. The outer edge of the bottom of the stirring rod 5 is flush with the inner wall of the reactor 1, meaning the bottom of the stirring rod 5 is arc-shaped. Material is added to the reactor 1 through the feed inlet at the top of the reactor 1. The output end of the drive motor 2 is connected to the rotating rod 3, and when the drive motor 2 rotates, it synchronously drives the rotating rod 3 to rotate. The rotating rod 3, in turn, drives the connecting rod 4 and the stirring rod 5 to rotate. Figure 3 As shown, when the stirring rod 5 is rotated by the rotating rod 3, the bottom end of the stirring rod 5 is in contact with the bottom end of the inside of the reactor 1, so that the stirring rod 5 can remain in contact with the inner wall of the reactor 1 when rotating, thereby allowing the material inside the reactor 1 to react fully and reducing the possibility of incomplete material reaction.

[0027] To address the problem of frequent leakage at the discharge point during long-term industrial application of existing reactors 1, which are generally equipped with top-discharge or bottom-discharge valves, bottom ball valves, or plunger valves for bottom discharge control, this embodiment proposes a discharge pipe 6 at the bottom of the reactor 1. A connecting pipe 7 is located at the bottom end of the discharge pipe 6, and the discharge pipe 6 and the connecting pipe 7 are fixedly connected by a docking mechanism. The connecting pipe 7 is equipped with a discharge mechanism for controlling material discharge. The docking mechanism includes two limiting rings 8 and two mounting rings 9. The two limiting rings 8 are fixed to the docking ends of the discharge pipe 6 and the connecting pipe 7, respectively. The two limiting rings 8 are two semi-circular cross-sections that can be joined to form a ring structure that engages the two mounting rings 8 on its inner side. That is, the ring structure can be separated into the two limiting rings 8. The two limiting rings 8 are connected and fixed by a positioning ring 10.

[0028] The upper ends of the two limiting rings 8 are attached to the discharge pipe 6 and bent to form a stepped portion. Multiple springs 11 are evenly installed on the inner side of the upper end of the limiting ring 8. One end of each spring 11 abuts against the stepped portion, and the other end abuts against the upper end of a movable ring 12. An elastic block 13 is installed between the lower surface of the movable ring 12 and the upper surface of the mounting ring 9 located above it. The lower ends of the two limiting rings 8 are attached to the discharge pipe 6 and form a stepped portion. Multiple springs 11 are evenly installed on the inner side of the lower end of the limiting ring 8. One end of each spring 11 abuts against the stepped portion, and the other end abuts against another movable ring 12. Another elastic block 13 is installed between the upper surface of the movable ring 12 and the lower surface of the mounting ring 9 located below it. The outer sides of the two limiting rings 8 are provided with external threads, and the inner side of the positioning ring 10 is provided with internal threads. The positioning ring 10 is screwed onto the two limiting rings 8 for connection and fixation, thereby locking the discharge pipe 7 and the discharge pipe 6.

[0029] Material discharge can be achieved using the discharge pipe 6. The discharge pipe can be connected to the connecting pipe 7 according to different needs, such as... Figure 7 As shown, the installation ring 9 and the limiting ring 8 on the outside of the discharge pipe 6 and the connecting pipe 7 restrict their position, ensuring a stable connection between them. The connecting spring 11 on the inside of the limiting ring 8 pushes against the corresponding movable ring 12, keeping the elastic block in contact with the installation ring 9, thus locking the position between the discharge pipe 6 and the connecting pipe 7. The threaded connection between the limiting ring 8 and the positioning ring 10 further locks the position between the discharge pipe 6 and the connecting pipe 7, achieving a stable connection and effectively preventing leakage during discharge, thus improving overall stability during use.

[0030] To address the potential issue of excessive material discharge leading to blockage during the reaction process, the leak-proof reactor 1 is equipped with a discharge mechanism. This mechanism includes a blocking block 14 that covers the end of the connecting pipe 7 and a spring-loaded assembly. By opening the spring-loaded assembly, the blocking block 14 is disengaged from the end of the connecting pipe 7, thus enabling the discharge of material.

[0031] The spring-loaded assembly includes a rotating rod 15, which rotatably passes through the connecting pipe 7 and extends out of the connecting pipe 7 at both ends. Multiple stirring blades 16 are radially mounted on the rotating rod 15 located inside the connecting pipe 7. A rotating wheel 17 is mounted at each end of the rotating rod 15 located outside the connecting pipe 7. The rotating wheel 17 is connected to a cam 18 via a synchronous belt. Two extrusion blocks 19 are correspondingly arranged on the outer side of the connecting pipe 7. The cams 18 engage with the corresponding extrusion blocks 19. The extrusion blocks 19 are not connected to the connecting pipe 7. An extrusion rod 20 is mounted at the bottom of each extrusion block 19. The bottom end of the extrusion rod 20 passes through a fixing block 21 and connects to a blocking block 14. The fixing block 21 is fixed to the side of the connecting pipe 7. A return spring 22 is sleeved on the extrusion rod 20, with one end connected to the extrusion block 19 and the other end connected to the fixing block 21.

[0032] To prevent material blockage caused by a single discharge, a discharge mechanism is used to discharge the material. Inside the discharge pipe 6 and the connecting pipe 7, the material impacts the stirring blade 16 with its own weight, causing the stirring blade 16 to rotate along the rotating rod 15. The stirring blade 16 disperses the material during rotation.

[0033] Next, the material falls onto the surface of the shielding block 14. When the material accumulates to a certain weight and the rotating rod 15 rotates once, the rotating wheel 17 rotates synchronously. The rotating wheel 17 drives the cam 18 to rotate through the belt pulley. When the cam 18 rotates, it will squeeze the extrusion block 19, thereby pressing the extrusion block 19 down. At the same time, the extrusion rod 20 extends downward simultaneously. During the downward movement of the extrusion rod 20, it will drive the shielding block 14 to move, thereby stopping the shielding block 14 from blocking the connecting pipe 7. The material is discharged from the bottom end of the connecting pipe 7, realizing the discharge of the material. This avoids excessive material discharge at one time, which may cause blockage. At the same time, it can also ensure that the material inside the reactor 1 can fully react before being discharged.

[0034] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
